Barrow joins fellow House Democrat Jim Matheson in announcing support for the contempt vote, and House minority whip Steny Hoyer has told reporters that other members of the Democratic caucus may vote "yes" on Holder's contempt charge. Sean Spicer, the communications director for the Republican National Committee, reports on Twitter that up to 20 House Democrats may vote "yes" on contempt.

Barrow, who is one of the most endangered congressional Democrats up for reelection this fall, also announced yesterday he will skip the party's national convention in Charlotte, North Carolina this September. That makes him part of the growing list of elected Democrats, including Senator Claire McCaskill of Missouri, choosing not to attend the party's convention.
